ListView的派生类 [英] A derived class from ListView

问题描述

我正在尝试创建一个自定义ListView类来解决闪烁和自定义绘制内容。



是否可以从ListView基类派生一个新类？类向导似乎反对：该类不能从托管类派生。这在C＃中是明智的。



IDE是VS 2012 Express，C ++

I'm attempting to create a custom ListView class to resolve flicker and custom draw stuff.

Is it possible to derive a new class from ListView base class? The class wizard seems to object: "The class cannot be derived from a managed class.". This was a no-brainer in C#.

The IDE is VS 2012 Express, C++

推荐答案

非常糟糕的问题 - 请看我对它的评论。



但是，在你澄清它之前：我怀疑你是试图从这个.NET FCL派生非托管类类。您应该使用托管ref类作为派生类。您可能对使用C ++ / CLI编写混合模式（托管+非托管）代码的可能性感到困惑。在学习如何混合之前，先编写托管代码。



我希望它会立即解决您的问题。如果没有，请不要怪我，而是准确地提出你的问题。

Pretty bad question — please see my comment to it.

However, before you clarify it: I suspect you are trying to derive non-managed class from this .NET FCL class. You should use a managed "ref" class as a derived class. You probably was confused by the possibility to write "mixed-mode" (managed + unmanaged) code with C++/CLI. Write just managed code, before you learn how to mix.

I hope it will immediately resolve your problem. If not, please don't blame me, pose your question accurately instead.
